Taken with the 100mm refractor and 2.5x powermate and 2x barlow stacked, there is a hot spot caused by the powermate, but given the awful seeing conditions when this image was taken, using the solar wedge with no ND filters keeps the exposure time at a minimum which does seem to be effective in freezing the moments of better seeing. This is something I will be exploring further in the future.
